Ths inventionrelates to new provements and structurai refinements ingasliquid admixing apparatus, and the principal bject of the inventionis to facilitate thorough and eiicient admixing of a liquid into a gas,such as for example, alcohol, gasoline, benzine, etc, into air, or the1ke, so that-the mixture derived from the apparatus is in the required,proper state of vaporization.

This object is achieved by the provision of an admixing apparatusincluding a tank containing a quantity of the liquid to be admixed,asubmerged aerating unit in the liquidin the tank, and a buoyant sprayngunit fioating on the liquid, matters being so arranged that air or someother gas is delivered to the aerating unit under pressure and iscausedto bubble upwardly through the liquid in the tank, whi1e at the sametime, iiquid from the tank is delivered under pressure to the sprayngunit andis dscharged thereby into the gas expelled by the aerator, sothat a thorough, efficient and complete admixing of the gas and liquidoccurs.

An important feature of the invention resides in the provision of meansfor condensing any improper1y vaporized liquid such as may 1eave thetank after the admixing operationand returning the condensation to theliquid in the tank for subsequent use.

An addtionalfature of the invention lies in its simplcty ofconstruction, ease and convenience of operation and. in its adaptabiltyto economical manufacture.

With the above more important objects and features in view and. suchother objects and features as may become apparent as the specificationproceeds, the invention consists essentaily in the arrangement andconstruction of parts as illustrated in the accompanying drawings, inwhich:

Figure 1 is a vertical cross sectional view of the invention,

Figur 2 is a cross sectional view, taken substantially in the plane ofthe line 2-2 in Fgure 1, and

Figure 3 is a cross sectona1 view, taken substantially in the plane ofthe line 3-3 in Figure 1.

Like characters of reference are employed to designate 1ik parts in thespecification and throughout the several views.

Referring n0w to-the accompanying drawings in gietail, the inventioncons sts of a gas-liquid admixng apparatus designateci generaily by thereference character 10, the same err1bodying in its construction anupright, substantially cylindrica1 tank I2 which is intended to receivein the 1ower portion thereof a quantity of 1iquidto be adrnixedthenormal level of which is indicated The upper end Wali 16 of the tank-l2carriesan electricmotor [8, the armatur ofwhich is coupldfito 'a sutableliquici.ipump 20 and als'o 1 Claim. 01. 261-121) and useful imthroughthe medium of a suitable gear box 2 2 to an air or gas compressor 24.

The intake duct 26 of ths compressor is equipped with a suitable filter2 8 whereby the duet communicates with the atmosphere, whi1e the out1etof the compressor communicates with a further duet 30. This duet extendsthrough the top wa1i |6 downwardly into the tank I2, and the lower endthereof carries and is in communication with a disk-like, substantiallycircular housing of an aerating unit 32.

It is to be noted that this aerating unit is submrged. with respect tothe 1iquid 1eve1 I4 and. that the circumferential wall of the aeratorhousin is formed with a plurality of outlet openingg 34. Moreover, asetof mutualiy divergent baiiie strips 36 are provided within theaerator housing 32,

these strips definng therebetween a plurality of air passages 38, eachof which extends from the 1ower end of the duet 30 to one of the outletopenings 34, as is best shown in Fgure 3. It is to be noted that inorder to facilitat this structural arrangement, the duet 30 iseccentricaily disinosed with respect to the aerator housing 32, as'wil1ba readily understood.

A spraying unit 40 floats upon the liquid in the housing 12, the unit 40including in its cohstruction a buoyant, disk-like member 42 on whichismounted a, circuiar chamber 44. This chamber,

in turn, is provided with a piurality of upwardly directed sprayingnozzles 46, and it is tob noted that the chamber 44 is also equippedwith an upright feed tube 48. The nozzles 46 are disposed above thelevel of the iiquid in the tank, and flotation of the unit 40 on theliquid safeguards against any possbility of the nozzies beingsubmerged.if the level of liquid sh0u1d rise.

A foraminous bafiie p1ate 50 is mounted in the tank I2 above thespraying unit 40, and the tube noted that suitable packing 56 isprovided in the upper end portion of the tube 40, in order to as- 'surethat all liquid delivered through th conduit 52 is conveyed, withoutleakage, through the tube 48 to the chamber 44.

A filtering sereen 58 is provided in the tankl2 above the foraminousbafiie 50, the conduit 52" passing downwardly through the sereen 58,whi1e the aforementioned duet 30 passes downWardly bafiie 50, as wi11 beclearly apparent.

The intake 00 of the pump 20 is conneted to a .feed tube 62, the latterextending downwardly through the screen58 as well asthrough the throughthe sereen 58 and throughthe -baflie 50 and carrying at its lower end afilter element 64 which is submerged. in the liquid in the tank I 2,

substantialiy as shown.
